Sensor ya CS3732 yoyendetsa ma conductivity

Kufotokozera Kwachidule:

electrode ndi sensa yofunikira yopangidwira kuyeza kuthekera kwa yankho lamadzi kuyendetsa magetsi, komwe kumagwirizana mwachindunji ndi kuchuluka kwa ma ayoni osungunuka. Chizindikiro chofunikira ichi ndi chofunikira poyesa kuyera kwa madzi, kuwongolera njira zamakemikolo, ndikuwunika kutsatira malamulo azachilengedwe m'mafakitale monga mankhwala, kupanga magetsi, chakudya ndi zakumwa, komanso kukonza madzi otayira.
Pakati pa elekitirodi ndi selo yoyezera yokhala ndi zinthu ziwiri zoyendetsera magetsi. Pamene magetsi osinthasintha agwiritsidwa ntchito, ma ayoni omwe ali mu yankho amamaliza dera pakati pa zinthuzi. Kuyendetsa magetsi komwe kumachitika kumayesedwa ndipo, pamodzi ndi geometric constant ya selo (cell constant, K), imagwiritsidwa ntchito kuwerengera kuyendetsa magetsi. Ma electrode amakono nthawi zambiri amaphatikizidwa ndi sensa ya kutentha (nthawi zambiri Pt100 kapena Pt1000 RTD) kuti apeze ndalama zokha, chifukwa kuyendetsa magetsi kumadalira kwambiri kutentha. Mapangidwe wamba amaphatikizapo maselo a pole ziwiri ogwiritsidwa ntchito nthawi zonse ndi maselo a pole zinayi (kapena ma electrode anayi), omwe amagwiritsa ntchito mphete za current ndi voltage zosiyana kuti achepetse zotsatira za polarization ndikuwonjezera mulingo woyezera, makamaka pakugwiritsa ntchito mphamvu zambiri.
